Description

Lifting fixture for live conductors of steel pipe towers for transmission lines

technical field

The utility model relates to an auxiliary tool for a power transmission line, in particular to a lifting jig for a steel pipe tower live wire of a power transmission line.

Background technique

The steel pipe tower is a transmission line tower that uses steel pipe profiles. At present, there is no special lifting fixture when the live wire fittings and insulator strings of the steel pipe tower of the transmission line are defective and need to be replaced.

Contents of the invention

In order to solve the problem that there is no special lifting jig for the live wire of the steel pipe tower of the transmission line, the utility model provides a lifting jig for the live wire of the steel pipe tower of the power transmission line.

The utility model is realized by adopting the following technical scheme: the lifting jig for the live wire of the steel pipe tower of the transmission line includes a horizontally arranged channel steel, and two left and right adjusting screw fixing shafts and two middle adjusting screw fixing shafts are worn on the two sides of the channel steel , the left and right two adjusting screw fixing shafts are specifically worn in the shaft holes, the middle two adjusting screw fixing shafts are specifically worn in the chute, and the middle two adjusting screw fixing shafts are both covered with inherent adjusting screws, and the two adjusting screws The lower end is connected to the fixed horizontal plate. Specifically, the adjusting screw passes through the fixed horizontal plate and is fixed by the adjusting nut. The two adjusting screw rods are covered with an inherent adjusting screw rod under the fixed shaft. The adjusting screw rod is provided with a screw rod handle, and the lower end of the adjusting screw rod The insulation adjustment rod is connected with the insulation adjustment rod, and the insulation adjustment rod and the adjustment screw rod are connected with the insulation adjustment rod fixing bolt through the adjustment screw rod. The lower end of the insulation adjustment rod is provided with an insulation adjustment rod adjustment hole, and the insulation adjustment rod adjustment hole is pierced with an insulation adjustment rod fixing bolt. , the lower part of the fixing bolt of the insulation adjustment pull rod is connected with a wire hook through a connecting rod.

When in use, place the channel steel horizontally on the cross arm of the steel pipe tower ground wire, move the adjusting screw in the chute to clamp the two adjusting screws on both sides of the cross arm and use the adjusting nut to fix the fixed horizontal plate on the steel pipe tower ground Then adjust the length of the two adjustment screw rods and the length of the insulation adjustment rod, hook the two wire hooks on the wire, and tighten the adjustment screw rod through the screw rod handle to lift the ground wire, which is convenient for replacement after the ground wire is lifted. Fittings or strings of insulators. The insulation adjustment rod plays the role of insulation.

The beneficial effects of the utility model are as follows: the lifting function of the live wire of the steel pipe tower of the transmission line is realized by using a reasonable lifting mechanism and an insulating structure. The structure and arrangement of the adjusting screw and the insulating adjusting rod are designed for the cross arm of the live wire of the steel pipe tower. The design of the adjusting screw greatly saves manual operation. The insulating adjusting rod not only provides the function of insulation but also has a certain adjustment ability. The utility model has the advantages of simple structure, safety and reliability, and is especially suitable for lifting live conductors of steel pipe towers of power transmission lines.
